There was this guy whom doubted the quran, sadly, after searching for answers, he still doubt the quran as the word of god. Now, convice that the quran is not the word of god anymore, he wants to write a book to present his doubt to the world so that the world will know his doubt and through his doubt, the world will judge the quran. how will you all advice him?
Tell him to write the book!
Apostasy from Islam hasn't yet become acceptable in many Muslim nations & families, in quite a few countries it carries the death penalty
so such books would help more Muslims feel that its perfectly allright to doubt or even leave Islam & there are people who have done that, besides the fact that if more & more such books are written- Muslims will be forced to accept that attempting to ban blasphemy or apostasy is futile & only makes them look foolish & violent which in its turn will encourage more Muslims to quit Islam.
